No. 484,238 filed Sept. 1, 1965, entited, Pipe Device, now abandoned.

This invention relates to smoking apparatus, more particularly the invention relates to pipes for smoking tobacco.

It is an object of the invention to provide a novel pipe which will act to feed additional air to the interior of the pipe for smoother burning of the tobacco therein.

It is a further object of the invention to provide a novel pipe having conduit structure to feed the air from the outside of the bowl of the pipe to the interior.

It is another object of the invention to provide a novel pipe with a cylindrical wall in the bowl which acts to conduct the air from the exterior of the bowl to the interior.

Further objects and advantages of the invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawing wherein:

FIG. 5 is a perspective view of the cylindrical cooling conduit structure of the bowl.

FIG. 6 is a side elevational view of a modified form of the pipe according to the present invention.

FIG. 7 is a partial cross-sectional view of the modified form of the pipe invention.

FIG. 8 is a partial bottom plan view taken along the line 88 of the bowl shown in FIG. 6 disclosing the bottom of the pipe bowl.

FIG. 9 is a partial bottom plan view taken along line 99 of the bowl shown in in FIG. 6 and illustrating the top of the pipe bowl.

Referring more particularly to the drawing, in FIG. 1, a pipe is illustrated having a conventional stem 21.

The stem 21 has a passageway or bore 22 which extends centrally along its length and communicates at its outlet 22' with the interior 26 of the bowl 23. The stem also has an outlet for the passageway at its other end 22".

The bowl 23 has a hollow interior 26 and its exterior 27 may be made of briarwood, ceramic material or other material suitable for pipes. A metal cylindrical wall structure 28 extends around the interior of the bowl. The wall structure 28 has a metal cylindrical inner wall 29 and a metal cylindrical outer wall 30 in spaced parallel relation thereto. Between the inner and outer walls 29 and 30 are a plurality of elongated metal spacer strips 31 which are positioned in a zig zag fashion along the wall structure 28 to form elongated passageway conduits or compartments 32. The outer wall 30 also has a frusto conical annular flange 33 along its edge 30 which extends inwardly over the top edge 29 of the inner wall 29 toward the interior of the bowl 23 and forms an air deflection flange. The wall structure 28 is open along its bottom so that air may travel into the wall structure 28 from the exterior of the bowl and upward between the walls 29 and 30 along the passages 32 between the strips 31 and be deflected inwardly by the deflection flange 33 into the interior 26 of the bowl to provide air to tobacco in the bowl for better burning. The wall structure 28 also has end strips 34 and 34' which simply form end walls and also extend the height of the inner and outer walls 29 and 30', excluding the deflection flange 33.

When the bowl 23 is filled with tobacco up to near the level of the top edge of the inner wall 29, the tobacco will be lighted by the smoker and as he smokes the pipe by drawing smoke from the bowl through the stem, the heat generated by the tobacco burning will heat the bowl, which in turn will heat the air in passageways 32 and cause air in the passageways to rise up the passageways and be deflected by the deflection flange 33 into the bowl.

The action of the air rising the passageway will allow more air to come into the passageways from the bottom and be heated and caused to rise and thereby provide a stream of air in the bowl to feed the fire of the tobacco in the bowl enabling a larger, more even, sustained burning of the tobacco and thus will reduce the likelihood of the fire in the bowl going out and will thereby reduce the need for repeated lighting of the tobacco being smoked.

The wall structure 28 also has an inner central circular metal disc 35 formed integrally at one edge 36 with the inner wall 29 and which disc extends along the bottom of the bowl. The center disc provides additional strength to the bowl. Above the disc 35 is a briarwood disc 27' which forms the bottom of the bowl.

The inner wall 29 of the wall structure 28 extends entirely around the bowl, with a notched out portion 28 to allow the passageway 22 to communicate with the interior 26 of the bowl. The outer wall 30 does not extend entirely around the bowl 23, but terminates with the end walls 34 and 34' on each side of the outlet 22 to enable the passageway 22 to communicate with the interior 26 of the bowl.

Thus, it will be seen that a novel pipe device has been provided, which provides more air to the tobacco in the tobacco bowl in a manner to produce more even burning and which also provides additional strength to the bowl.

The modified form of the pipe device is illustrated in FIGS. 6-9 inclusive. The modified pipe 40 has a pipe bowl 41 and a pipe stem 42. The pipe bowl 41 is formed of two metal parts, an outer annular bowl or cup-like metal member 43 and an inner bowl or cup-like metal member 44. The outer portion member 43 is formed of steel or any other suitable heat resistant metal, and is formed in one piece having an annular outer wall portion 45 with a slight inwardly tapered upper edges 45' and a bottom wall portion 45" having a rounded recess 46 bulging upwardly into the bowl member 43 with its center 46' abutting the bottom wall 41' of the inner bowl 44. The recessed portion 46 of the bottom wall 45" of the outer bowl, has eight holes 47 therethrough spaced equally about the circumference of the recess 46.

The inner bowl 44 has eight triangular openings 48 spaced about the circumference of the annular wall 44' of the inner bowl. The eight openings 8 are formed by V-slits 48' in the side wall 44" by bending outwardly and downwardly the triangular surfaces 8" of the side wall 44 disforming it, until the tip 8" of the triangular surfaces abutt the outer bowl 43, it will provide an inclined deflecting action whereby air may pass upwardly from the outside of the pipe bowl 40, upwardly through the holes 47 along the annular space 49 between the inner and outer bowls 43 and 44 and pass from the annular space 49 through the openings 48' to provide air into the interior of the bowl 44 where the pipe tobacco is placed to create more even burning of the tobacco. Also this circulation of the air in the inner and outer bowls tend to maintain the outer bowl sufllciently cool so that it may be kept cool and the operator may handle it without burning his fingers or hands.

The inner bowl has an outwardly extending annular flange 50 formed integrally with the inner bowl 44 and has a peripheral portion which abutts the inclined side portions 45 of the outer bowl, the inner and outer bowls 43 and 44 are mounted together by inserting the inner bowl 44 into the outer bowl 43 to their positions shown in FIG. 7 and connecting the respective bases 41' and 46 together by rivet 51. After the two bowls have been riveted together, the outer bowl 43 is then tapered inwardly to its position shown in FIG. 7 allowing the upper annular edge 45' to firmly lock the upper portions of the bowls together. The pipe 40 has a conventional mouthpiece 52 with a hollow passageway 53 therethrough and with an inner metal sleeve 54 with the forward end 54 f the inner metal sleeve being received within, the stem 55 which is fixed to the bowl 40. The stem 55 has an inner metal tube 56 which communicates with the interior of the inner bowl 44. The tube 56 has a radially extended flange 56' in its forward end to lock the tube 56 to the bowl 40. The outer sleeve portion 57 of the stem 55 surrounds the tube 56 and is press fitted to the tube 56 with the forward edge of the outer sleeve abutting the exterior of the inner bowl. The outer bowl 43 has a hole 58 for receiving the inner and outer sleeves 56 and 57, whereby smoke may pass or may be drawn from the interior of the inner bowl 44 through the bore 53' of the stem 55 and along the 4 bore 53 of the mouthpiece 52 through the outer end 52' of the mouthpiece 52 of the pipe.

The stem may have its outer surface formed of a heat absorbing material such as briarwood. Also, the outer sleeve 57 of the stem 55 may be made of briarwood, if so desired.
